UNITED STATES PATENT OFFICE DRAFT SHIELD Randall R. Scharmen, San Antonio, Tex. Application July 21, 195o, serial No. 175,197

1 Claim. (Cl. 98-2) This invention relates to draft shields,` and has for one of its objects the production of a simple and ecient shield which may be easily and quickly attached to the door frame of an automobile, at the window portion thereof and selectively adjusted to direct air into the car and to cut-olf the draft when desired.

A further object of this invention is the production of a simple and efficient attaching means for supporting a draft shield upon the door post of an automobile in a manner whereby the draft shield may be easily adjusted, installed, or removed.

Other objects of the present invention will appear throughout the following specification and claim.

In the drawings:

Figure 1 is a perspective view of the draft shield mounted in position upon a door post, portions of the adjoining parts of an automobile being shown;

Figure 2 is a top plan view of the shield attaching clamp, a portion of the door and frame of an automobile being shown in section and the journal barrel also being shown in section;

Figure 3 is a fragmentary edge elevational view of the shield and clamp, a portion of the door post being shown in edge elevation;

Figure 4 is a vertical sectional View taken on line 4-4 of Figure 3;

Figure 5 is a fragmentary horizontal sectional view taken through the window portion of an automobile door and support showing the draft shield in position relative to the conventional forward pivoted draft panel;

Figure 6 is a top plan view of a modified form of clamp, a portion of the door post and support being shown in section; K Y l Figure 7 is an enlarged vertical sectional View taken on line I-'I of Figure 6;

Figure 8 is a fragmentary side elevational view of the vane and hinge portion for engaging the supporting clamp.

By referring in detail to the drawings, it will be seen that I designates a conventional door post of an automobile door II. A detachable clamp I2 is adapted to grip the door post I0 in the manner shown in Figures 1, 2 and 5. The clamp I2 comprises a curved or rolled jaw I3 which is adapted to grip the inner rounded vertical face of the post I0. The clamp I2 is provided with an outwardly protruding vertical bushing receiving portion I4 in which a Vertical bushing I is welded. An outwardly inclined bracing portion I2a connects the bushing receiving portion I4 to the jaw I3. The clamp I2 also is provided with a post abutment strip I6 which is carried by the leg I8 of the clamp I2 and adapted to rest against the outer face of the post I0, as shown in Figure 2. The strip I6 is provided with an angle portion I 6a which is secured to the inclined bracing portion |25. The leg I8 is carried by the bushing receiving portion I4, as shown in Figure 2. A clamping plate I1 is adjustably secured to the leg I8 of the portion I4 by a securing means such as a bolt I9. A vertical rolled edge 2li is carried by the plate II'I to engage the outer edge of the post I0 and thereby securely anchor the clamp I2 upon the post I0, as shown in Figure 2.

A vane 2l of glass or other transparent material is supported by a pintle 22. The pintle 22 carries an integral vane supporting brace 23, which brace 23 engages the inner face of the Vane and is integral with the head 24 of the pintle 22. A bracing plate 25 is clamped against the outer face of the vane 2| and the two braces are secured in clamping engagement with the vane 2I by means of suitable rivets 26. A friction washer 21 of composition, fiber, or rubber, is interposed between the head 24 and the upper end of the bushing I5. The bushing I5 terminates short of the lower end of the clamp I2, defining a socket 29 at the lower end thereof, as shown in Figure 4, and a coil spring 28 is fitted in the socket 29 upon the lower end of the pintle 22. The coil spring 28 abuts the lower end of the bushing l5 and a knurled nut 30 is threaded upon the lower end of the spring 28 and the nut 30. The Atension of the spring 28 may be regulated to hold the'head 24 of the pintle 22 in tight frictional engagement with the washer 2'I and to thereby hold the vane in an adjusted angular position relative to the window opening of the' door Il. The vane is of aheighth to readily swing into the windowopening of the door I I from the: position shown in full lines in Figure 5 to the dotted line position thereof. i.. i

It should be noted that the clamp I2 may be readily adjusted and positioned upon or removed from and attached to the door post I0 by means of the adjustable or attachable plate 20 and bolt I9. The angular position of the Vane relative to the window opening of the door II may also be regulated or adjusted by rotating the spindle 22 and tightening the nut 30. The vane ZI may be easily swung when the nut 30 is loosened and may then be locked at the desired angle by tightening the nut 3.

Incarrying out the invention, the clamp I2 is secured to the door post rearwardly of the conventional forward pivoted draft panel 3|. The panel 3| is adjusted at a desired angle to regulate the now of air and the vane 2| is then placed at a desired position to direct the air substantially parallel to the outside of the automobile, away from the automobile or into the automobile. Since the vane 2| is mounted on the rear post i0 of the door currents of air will not strike the rear post Ill.` with great force, but the air will be guided through the space between the vane 2| and the outside of the automobile when the parts are in the position shown in Figure 5. By adjusting the panel 3| and vane 2|, the air cur'- rents may be directed into any part of the car or automobile when desired, or all draft through the car or automobile may be shut-ofi entirely and directed outwardly. If desired, the panel 3| and vane 2| may be in any color to add to their appearance. The vane 2|v may be easily adjusted, installed, or removed,` and' will' not marv the nish of the automobile to which it is attached.

In Figures 6, '1, and` 8, there is shown a modified form of the invention, wherein a clamp 32 engages the corner door postv ma. Ther clamp 32 is provided with a curved or rolled jaw which snuglyfits around the outer roundedvertical face of the post lila, in a manner similar to that. form shown in Figure 2. A clamping plate 34 similar to the clamp |1 secures the clamp. 32' to the opposite side edge of` the post |05. In thisform, shown in Figures 6 and '1, a metal casting 35 is secured to the clamp 32the clamp 32: being inset for a portion of its length into the abutting face of the casting 35 to facilitate the anchoring of the parts together.

The casting 3,5 supportsv a pintle or journal' pin 36, and this pintley is providedy with a square neck head'Sa for anchored connection with the connecting head 31 of the vane brace 38' to which brace the transparent vane 2N is secured, as shown in Figure 8. The head 31 is connected to the brace` 38 whichl engages one face of the vane 21a andthe head 31 isv connected to the brace 38 by means of an angularly extending or inclined neck 39. A companion brace 38a engages the opposite face of the vane 2|a. Suitable rivets anchor the braces. and vane together in a manner defined with respectY to the structure shown in Figures' 1 and 3. A friction washer 4|) is interposed between the upper end of the casting 35 and the lower face of the head131.

The casting 35' is provided with a socket 4| at its lower end, as shown in Figure 7, and a coil spring 42 is seated in this socket 41|k upon the lower end of the pintle 36. An adjusting knurled nut 43 is threaded upon the lower end' of the pintle 36 to adjust the tension of the spring 42 and to facilitate thel locking. of the pintle 38 and vane 2 a carri-ed thereby in a selected angular position relative to the window opening of its supporting door. A washer 44 is interposed between the spring 42 and the nut 43.

From the foregoing description it will be seen that a simple and efficient detachable hinge connection is provided for attaching a wind or air current deecting vane to the outside face of a door post adjacent the window thereof, so that the vane may be frictionally locked in a selected angular position having a portion thereof protruding through the window or having the entire vane located outwardly of the window. In this structure, the air mayy be directed into and through the window or the air may be directed outwardly through the proper adjustment of the forward panel 3 It. should be understood that certain detail changesV in the arrangement of parts and construction of the device may be employed without departing from the spirit of the invention, so long as such changes fall within the scope of the appended claim.

Having described the invention, what I claim as new' is:y

A drafty shield support comprisingl a clamp adapted to grip the door post of a vehicle, said clamp comprising. a curved jaw` adapted to grip theinner rounded vertical face. of a post, an outwardlyinclined. bracing portion supported by said curved jaw, an outwardly protruding vertical bushing receiving portion supported by said bracing portieri, a vertical bushing fixed in said bushing receiving portion, a leg carried by said bushing receiving portion, a post abutment strip carried by said` leg and having` an angle portion secured to said inclined bracing portion, a clamping plate, a bolt adjustably securing said clamping plate to said leg, a vertical rolled edge carried by said clamping plate adapted to engage the outer edge of a post to securely anchor said clamp. upon a post, a vane, a pintle journaled upon said vertical bushing, a head carried by said pintle and supporting said vane, a friction washer interposed between said head and one end of said bushing, ay spring carried by said pintle and engaging the opposite end of said bushing, and a nut adjustably threaded upon said pintle and engaging saidk spring to regulate the tension of said spring to adjustably lock said head and bushing in engagement with said friction washer and to thereby secure the pintle in a xed position within said bushing and to hold said vane in a selected adjusted position toward and away from the door post.
